Wind-up twizzle-stick (7)
I believe the answer is:
stirrer
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for stirrer that I've seen before include "engineering several revolutions in Darjeeling?" , "Scaremonger" , "One who spreads frightening or malicious rumours" , "One making solution perhaps" , "Spoon - agitator" .)
